Why do microbiologist often disinfect work areas before working with bacterial cultures?
Microbiologists disinfect work areas before handling bacterial cultures to prevent contamination and ensure the integrity of their experiments. This practice minimizes the risk of introducing unwanted microorganisms that could interfere with results or pose safety hazards. Additionally, disinfection helps protect the researcher from exposure to potentially pathogenic organisms. Overall, maintaining a sterile environment is crucial for accurate and reliable scientific outcomes.

Why does penicillin not affect human cells?
This is essentially because bacterial cells and human cells are very different. Both bacterial and human cells use chemicals called enzymes to build their walls. Penicillin is the right chemical "shape" to chemically stick to part of the bacterial enzyme. When it does this, it stops the bacterial enzyme from working properly and this makes the bacterial cell walls weak. The weakened cell wall cannot withstand the outside pressure, it breaks up and the bacterial cell dies. Human cells are made by different types of enzymes with a different chemical shape that penecillin is unable to stick to so it cant stop the human enzymes from working. The human cell walls are thus unaffected by it and they remain strong.
What do you wipe down before leaving the laboratory?
Before leaving the laboratory, it is important to wipe down and disinfect any surfaces you have come in contact with, such as equipment, benchtops, and door handles. This helps prevent the spread of contaminants and ensures a clean and safe working environment for the next person to use the space.

Can you incubate petri dishes at room temperature?
Yes, you can incubate petri dishes at room temperature for certain types of cultures that do not require specific temperature conditions. Make sure to check the temperature requirements of the specific culture you are working with before incubating at room temperature.
What is an example of unity in diversity?
An example of unity in diversity is a company that embraces employees from various cultures, backgrounds, and perspectives, all working together towards a common goal. This diversity fosters innovation, creativity, and a welcoming work environment that values different viewpoints and experiences.
What are the precautions when working with bacteria?
When working with bacteria, it is important to wear appropriate personal protective equipment such as lab coats, gloves, and safety goggles. Always work in a designated area such as a biosafety cabinet to minimize the risk of contamination. Properly dispose of all biohazardous waste in designated containers and follow established protocols for handling, storing, and disposing of bacterial cultures. Regularly disinfect surfaces and equipment to prevent cross-contamination.
